Chapter 2. PIC18 Wireless Development Board

2.1 BOARD LAYOUT AND FEATURES

This chapter describes the PIC18 Wireless Development Board hardware, which

features the components shown in Figure 2-1.

FIGURE 2-1: PIC18 WIRELESS DEVELOPMENT BOARD

8-Bit Wireless Development Kit User’s Guide

The PIC18 Wireless Development Board supports the XLP microcontroller options

such as PIC18F46J11, PIC18F46J50, PIC18F46K20 and PIC18LF45K22.

The default microcontroller option is PIC18F46J50. Different microcontroller options

require different components to populate on the board.

The following main blocks are defined on the Board:

• Serial Accessory Port

• USB Interface Port

• PICtail Port

• Push Buttons

• Onboard Temperature Sensor

• Onboard Serial EEPROM

• Debug LEDs

• Power Supply

2.1.1 Serial Accessory Port

Serial Accessory Port provides a simple serial interface for the external modules.

These modules may be either external sensor or accessory board. For more

information about existing accessory boards turn to http://www.microchip.com or refer

to the “LCD Serial Accessory Board User’s Guide” (DS70650A) or “RS232 Serial

Accessory Board User’s Guide” (DS70649A).

The following interfaces are supported by the Serial Accessory Port:

• 3 or 4 wire SPI

•I

2C™

• USART

These interfaces are selected by the software without modifying the hardware. User

should be attentive when different interfaces use the same hardware of the

microcontroller or share the same port pins. For more information on the port pin

assignment, see Figure A-1.

2.1.2 USB Interface Port

PIC18F46J50 microcontroller provides USB v2.0 compliant full speed Universal Serial

Bus (USB) interface which aid in provides power to the Board. The relevant USB

components are included with the PIC18F46J50 microcontroller option.

Note 1: Missing components on the board does not indicate a defect. Population

of these missing components depend on the Microcontroller being used.

For more information about using different Microcontrollers, see the

Section A.2 “PIC18 Wireless Development Board Schematic”

2: Extra care is required while changing the microcontroller option as

improper tools or poor handling could harm the copper tracks on the

surface of the Board, it might destroy it.

PIC18 Wireless Development Board

2.1.3 PICtail Port

PICtail Port is a 28-pin interface port that supports Microchip's RF based daughter

cards. PICtail Port provides the following interfaces to the daughter cards:

• Power supply

• SPI interface

• Interrupt request lines

2.1.4 Push Buttons

PIC18 Wireless Development board contains push buttons, RB0 and RB2, that are

assigned to the individual interrupt lines of the microcontroller. These buttons are not

driven by external pull-up circuitry to save power consumption. The user software must

enable the Port B pull-ups of the microcontroller prior to evaluating the button state.

Example 2-1 illustrates a possible solution to evaluate the state of RB2.

EXAMPLE 2-1: CODE EXAMPLE FOR EVALUATING THE STATE OF RB2

2.1.5 Onboard Temperature Sensor

The temperature sensor used is the Microchip's MC9700A, which is a Low-Power

Linear Active Thermistor™ IC. To provide the smallest power consumption, the sensor

is powered from a port pin. After powering up, the sensor output can be measured after

waiting for 1 minute delay. The internal AD converter of the microcontroller is used to

measure the temperature value.

2.1.6 Onboard Serial EEPROM

The Onboard Serial EEPROM is a low power Microchip 25LC256 256K SPI Bus Serial

EEPROM which shares the SPI interface with the PICtail Port, but it has its own active

low chip select line connected to the RD5 port pin.

2.1.7 Debug LEDs

The Board contains three LEDs for debug purposes. To conserve battery power, LEDs

power can be disconnected by removing the JP201, LED Power jumper.

Note: User must be careful about the PICtail port pins that share different

functions of the Board. The user needs to check the schematics before

assigning functions for any port pins.

//Initialize RB2

TRISBbits.TRISB2 = 1; // RB2 is an input

ANCON1 |= 0x01; // RB2 is a digital pin

/* User code

//Evaluating RB2

INTCON2bits.RBPU = 0; // PortB pull ups are enabled

if (PORBbits.RB2 == 0) // RB2 is pushed

{/* RB2 PB code...

}

INTCON2bits.RBPU = 1; // PortB pull ups are disabled

8-Bit Wireless Development Kit User’s Guide

2.1.8 Power Supply

The board can be powered from one of the following sources:

• 2xAA onboard battery pack can be found at the bottom side of the board

• USB port

• External 9-16V charger power supply through the standard coaxial power

connector

• External 3.0-3.6V power source through test points TP301 and TP302

USB Port and external coaxial port power are stabilized by MCP1703, 250 mA, 3.3V,

low quiescent current LDO regulator. The battery operated applications that do not

require LDO can be disconnected by removing the JP301, Regulator Disconnect

jumper.

2.1.8.1 CURRENT CONSUMPTION MEASUREMENT

The board contains two jumpers, JP302 and JP303, to measure the current

consumption of the kit. These jumpers give the opportunity to measure current

consumption of the entire kit without disturbing it.

To measure the operational current follow the following steps:

1. Ensure that either JP302 or JP303, has one jumper connected to it. Only one

jumper is required.

2. Connect the current meter to the jumper that is empty. Because the jumpers are

electrically parallel, it can be either JP302 or JP303.

3. Set the current measure range of the current meter higher than 250 mA.

4. Remove the jumper.

Note: The 9V wall adapter is not included in the kit. A 9V wall adapter may be

ordered from www.microchipdirect.com under part number AC162039.

Note: Some current meters set the measuring range automatically, which can

cause interruptions in the power line while changing the range. If

interruption in the power line occurs, use manual range settings.

• MCP9700A Temperature Sensor

• MAC Address EEPROM on MRF24J40 Daughter Boards

• LCD Serial Accessory Board

3.4.1 Creating a MiWi Network

3.4.1.1 TO CREATE A MiWi NETWORK

Follow these steps to create a MiWi Network:

1. Configure one node as PAN Coordinator (“Create NWK”) and another as

Coordinator (“Join NWK”).

2. Use the Coordinator to join the PAN Coordinator. The “8-bit Wireless Develop-

ment Kit” message will display on the LCD after powering the nodes. After a few

seconds the display changes to:

• RB0: Create NWK

• RB2: Join NWK

3.4.1.1.1 To Configure the node as PAN Coordinator

Follow these steps to configure the node as PAN Coordinator

1. On one node press RB0 push button to create the network.

After the node is configured as PAN Coordinator, “Created Network

Successfully” message will display on the LCD. After the device is configured as

PAN Coordinator, it measures the temperature sensor for every 30 seconds and

updates the LCD with the temperature information in °C (Celsius) and °F

(Fahrenheit). The last 3 bytes of the MAC Address in HEX format are also

displayed on line two of the LCD:

• Local Temp

• 010203: 21C/ 70F

3.4.1.1.2 To Join the network as Coordinator

Follow these steps for joining the network as Coordinator

1. On the second node press RB2 push button to join available networks. This

initiates an active scan command. The available network information will be

displayed on the LCD:

• RB0: (PC) 010203

• RB2: Addtnl NW-0

2. Press RB0 to join PAN Coordinator, with the address 0x010203, created in the

previous step.

The LCD displays “Joined Network Successfully”. After the node is successfully

joined the PAN Coordinator, it measures the temperature sensor for every 30

seconds and broadcasts the information over the network along with its MAC

Address. The LCD is also updated with the temperature sensor reading:

• Local Temp

• F1F2F3: 20°C/ 68°F

Getting Started

3. Press RB2 to display the remote temperature (PAN Coordinator):

• Remote Temp

• 010203: 21°C/ 70°F

3.4.2 MCP9700A Temperature Sensor

This demo uses the on-board MCP9700A Temperature Sensor. The readings are noted

every 30 seconds and the information is broadcast in the network. Both the nodes store

the local and remote temperature data and display it on the LCD.

To re-measure the temperature value, press RB0 push button on the PIC18 Wireless

Development Board. This also initiates the broadcast message to all the nodes in the

network. To scroll through the rotating display of local temperature and remote

temperature use RB2 push button on the PIC18 Wireless Development Board. The

two node network can also be expanded to a multi-node network, for more information,

see tutorial in Section 4.7 “8-bit Wireless Development Kit with Additional

Nodes”.

3.4.3 MAC Address EEPROM on MRF24J40 Daughter Boards

All the MRF24J40 daughter cards have a MAC Address EEPROM. The 6 byte MAC

Address in this EEPROM is used for the addressing scheme in MiWi.

3.4.4 LCD Serial Accessory Board

The LCD Serial Accessory board can be used either in the SPI or I2C mode. This demo

uses the LCD Serial Accessory Board in I2C mode. The demo uses manual backlight

mode versus the automatic backlight mode. With the manual backlight mode, the

power consumption can be kept to the minimum.
